T0 aZZ whomV t may concern.

Be it known that I, FRIEDRICH Kn'HLEs, a citizen of the United States, and a resident of Maywood, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Non- Reiillable Bottles, ofwhich the following is a specification.

This invention relates to a non-rellable bottle, which is of simple construction and reliable in operation.

In the accompanying drawing: Figure 1 is a longitudinal section of the upperv part of a bottle embodying my invention; Fig. 2

a side view of thesleeve; Fig. 3 a cross sec-V tion online 3 3 Fig. 1, and Fig. 4 a cross section on line 4`4 Fig. l.

VThe device comprises essentially a tubu- 3, and of such a diameter as to form an annular discharge passage ,4' therebetween.v At its lower edge this passage is closed by an annular packing ring or iiexible gasketv 5 that is seated within a groove 6 of neck 2, and serves as a means for centering the sleeve within the neck. Within sleeve 1 isv accommodated, a freely movable float valve 7 which is adapted to rest upon a, seat v8 formed within the lower part of the sleeve. This valve is composed of a hollow sphere of glass,or similar material, which is adaptn ed to iioat upon the liquid, and will notinjuriously a'ect the same. Withinsleeve 1 is further accommodated, a freely movable weight 9 which is likewise composed Vof a` sphere of glass or similar material, but is made solid, so that it will not float upon the liquid. Weight 9 rests normally on oat 7 as indicated in Fig. 1.

Into the top of sleeve l, there is fitted, a plug 10, having a number'of ports or apertures l1, and provided with a neck carrying a disk 12, that is slightly larger than the diameter of sleeve 1, so as to prevent tampering with the contents of the sleeve. When the bottle is righted, weight -9 will rest on float 7, and the latter in turn will rest on the float becomes re-seated.. When the bottle is, forv refilling purposes,` tilted with its neck held downward, *the vfloat will rise with the ingress of the liquid and settle against seat 8. When 'the bottle is, for refilling purposes, tilted with its neck'held upward, the weight9 will descend and thus force the float against the seat. In this way, the spurious reiillingof the bottle in Y all positions, is prevented in a neat and ree l liable manner, while the outflow of the liquid is in no wiseunduly hampered. To asfl semble the parts, gasket isi-slipped over sleeve 1 so as to rest upon a bottom flange of the same, while plug 10 is introduced into thetop vof the sleeve, with its neck and disk extending beyondv the top thereof. The sleeve is now lowered into the bottleneck,

accommodated by clearance 4f, within rwhich itis compressed, until it reaches groove 6,

where it will expand to lock'the sleeve to the bottle.- The disk V12 by extendingV across the bottle neck over passage 4, will [prevent the introduction of a tool for-the purpose of tampering with the (device. Iclaim: i A non-reiillaV le bottle having a neck provided with a lowergroove, a sleeve centered within said neck and of a-diameter to formV an annular passage therebetween, a flexible gasket encircling the sleeve and adapted to Y Specification of Letters Patent. Patented 0G15 19, 1915.

,Seat s. whe'nthe bottle is tilted, Weight 9 6o y Y Y duringwhich operation .the gasket 5, will be 'Y be projected into said lower groove through said annular passage, a valve seat formed in 'the sleeve, a spherical float adapted to engagethe seat, a spherical weight adapted `to engage the float, an' apertured plug fittedv into the top of the sleeve, a neck extending upwardly from the plug, and a disk carried by the neck and projecting over the sleeve.
